具体实施方式detailed description
下面结合附图对本实用新型作进一步说明。Below in conjunction with accompanying drawing, the utility model is further described.
如图1、2所示，本实施例提供了一种智能节能电风扇系统，包括电风扇主体、红外人体感应模块、温度感应模块、声音感应模块以及控制单元，所述控制单元包括上位机和下位机，所述下位机包括主控芯片、传感器的辅助控制芯片和风扇的辅助控制芯片，所述主控芯片通过串口与上位机相连，所述主控芯片分别与传感器的辅助控制芯片和风扇的辅助控制芯片相连，所述传感器的辅助控制芯片分别与温度感应模块、红外人体感应模块、声音感应模块相连，所述风扇的辅助控制芯片与风扇主体的电子调速电路相连。As shown in Figures 1 and 2, this embodiment provides an intelligent energy-saving electric fan system, including an electric fan main body, an infrared human body sensing module, a temperature sensing module, a sound sensing module, and a control unit, and the control unit includes a host computer and The lower computer, the lower computer includes a main control chip, an auxiliary control chip of the sensor and an auxiliary control chip of the fan, the main control chip is connected with the upper computer through a serial port, and the main control chip is connected with the auxiliary control chip of the sensor and the fan respectively. The auxiliary control chip of the sensor is connected with the temperature sensing module, the infrared human body sensing module and the sound sensing module respectively, and the auxiliary control chip of the fan is connected with the electronic speed regulating circuit of the fan main body.
所述红外人体感应模块，采用被动式红外热释传感器，检测人体是否在风扇工作区，将信息传递给传感器的辅助控制芯片，控制单元进行反馈决定电风扇的开合状态。The infrared human body sensing module uses a passive infrared thermal sensor to detect whether the human body is in the working area of the fan, and transmits the information to the auxiliary control chip of the sensor, and the control unit performs feedback to determine the opening and closing state of the electric fan.
所述温度感应模块通过温度感应器来检测环境的温度，首先设定临界值，当夏天温度达到临界值时，温度感应模块将感应到的温度传到控制单元，控制单元判断温度是否达到临界值，若温度达到临界值则系统将其与其他数据(检测到的人员信息、声音信息)结合使风扇自动打开，并与其他信息综合处理调节到相应档位，依次有五个档位的温度临界值，以适应不同的环境温度达到更好的调节作用。反之，风扇处于关闭状态，不打开；The temperature sensing module detects the temperature of the environment through a temperature sensor, and first sets a critical value. When the summer temperature reaches the critical value, the temperature sensing module transmits the sensed temperature to the control unit, and the control unit judges whether the temperature reaches the critical value. , if the temperature reaches the critical value, the system will combine it with other data (detected personnel information, sound information) to automatically turn on the fan, and adjust it to the corresponding gear through comprehensive processing with other information. There are five gears in turn for temperature critical Value to adapt to different ambient temperatures to achieve better regulation. On the contrary, the fan is off and not on;
所述声音感应模块包括在每个电风扇的颈部安设声音传感器，该传感器内置一个对声音敏感的电容式驻极体话筒。声波使话筒内的驻极体薄膜振动，导致电容的变化，而产生与之对应变化的微小电压。这一电压随后被转化成0-5V的电压，经过A/D转换被数据采集器接收，并传送给传感器的辅助控制芯片。所述传感器的辅助控制芯片将声音传感器的信号传递到上位机的控制系统后，与温度感应模块以及系统内自带的是否为上课考试时间等信息进行综合处理后，判断出此时教室内是否需要降低或加快风扇风速，从而形成对风扇转速的辅助性工作；The sound sensing module includes installing a sound sensor on the neck of each electric fan, and the sensor has a built-in condenser electret microphone sensitive to sound. Sound waves vibrate the electret membrane inside the microphone, causing a change in capacitance, which produces a corresponding change in tiny voltage. This voltage is then converted into a voltage of 0-5V, received by the data collector through A/D conversion, and sent to the auxiliary control chip of the sensor. After the auxiliary control chip of the sensor transmits the signal of the sound sensor to the control system of the upper computer, after comprehensive processing with the temperature sensing module and the information such as whether it is the time of class and examination that comes with the system, it is judged whether the classroom is at this time. It is necessary to reduce or increase the fan speed to form an auxiliary work on the fan speed;
上位机的控制系统作为整个系统的核心，起到数据处理及发出操控指令的作用，同时将当前状态信息时时呈现给管理员，方便管理员对系统进行必要的配置。As the core of the entire system, the control system of the upper computer plays the role of data processing and issuing control instructions, and at the same time presents the current status information to the administrator from time to time, which is convenient for the administrator to configure the system.
主控芯片采用STM32F103RBT6芯片，它具有高达72MHZ主频，丰富的外设(包括串口、SPI接口、IIC接口、AD转换、定时器等)，其运算处理功能强大，通信功能完善，能够满足设计需要；与上位机通信时，采用的是串口，打开IO时钟和串口时钟，并设置好相应的中断及编写中断处理函数，就可以实现上、下位机的发送与接收数据的功能。The main control chip adopts STM32F103RBT6 chip, which has a main frequency of up to 72MHZ, rich peripherals (including serial port, SPI interface, IIC interface, AD conversion, timer, etc.), its powerful operation processing function, perfect communication function, can meet the design needs ; When communicating with the upper computer, the serial port is used, open the IO clock and the serial port clock, and set the corresponding interrupt and write the interrupt processing function, then the function of sending and receiving data from the upper and lower computers can be realized.
传感器的辅助控制芯片采用STC89C51芯片，由它实现对传感器收集到数据初步处理，并传输到主控芯片，或是接收主控芯片传递的操控指令，对传感器的相关参数进行适当的调整。The auxiliary control chip of the sensor adopts the STC89C51 chip, which realizes the preliminary processing of the data collected by the sensor, and transmits it to the main control chip, or receives the control instructions transmitted by the main control chip, and properly adjusts the relevant parameters of the sensor.
风扇的辅助控制芯片采用NE555型时基集成电路。该电风扇电子调速器电路由电源电路、可控振荡器和控制执行电路组成。The auxiliary control chip of the fan adopts NE555 type time base integrated circuit. The electric fan electronic governor circuit is composed of a power supply circuit, a controllable oscillator and a control execution circuit.
上位机的控制系统根据当前系统时间判断是否是在夏季时间段内，若在则系统工作，不在则系统不工作。The control system of the upper computer judges whether it is in the summer time period according to the current system time. If it is, the system will work, and if it is not, the system will not work.
若系统时间在夏季时间段内，则当红外人体感应模块感应到人时，控制系统打开温度传感器开关，温度传感器开始工作，将温度信息传给主控芯片，当检测的温度在人的最佳体感温度附近，或是温度较低时，风扇不工作；当气温高于设定阈值时，由主控芯片根据气温等数据计算出使得人处在最适体感温度范围内的适宜的风扇转速并控制风扇达到适宜的转速，虽然风扇转速的调节可以采用无级制，但实际采用的是多级制，既防止因为温度的频繁变化而频繁的调节风扇转速，也避免了风速不是太大就是太小的尴尬，同时控制系统能根据实际情况调整所需的级数，更加智能化、人性化。If the system time is in the summer time period, when the infrared human body sensing module senses a person, the control system turns on the temperature sensor switch, the temperature sensor starts to work, and transmits the temperature information to the main control chip. The fan does not work when the temperature is close to the body temperature, or when the temperature is low; when the temperature is higher than the set threshold, the main control chip calculates the appropriate fan speed to make people in the most suitable temperature range based on the temperature and other data Control the fan to achieve a suitable speed. Although the adjustment of the fan speed can be stepless, the actual use is a multi-level system, which not only prevents frequent adjustment of the fan speed due to frequent temperature changes, but also prevents the wind speed from being too high or too high. Small embarrassment, at the same time, the control system can adjust the required series according to the actual situation, which is more intelligent and humanized.
声音感应模块检测风扇产生的噪声大小，根据事先在上位机控制系统中输入的当前教室当前时间段应处的状态信息(如上课、考试、开放自习和关闭等)来调整风扇转速，直至风扇产生的噪声大小满足相应状态的要求。The sound sensing module detects the noise generated by the fan, and adjusts the fan speed according to the state information (such as class, exam, open self-study and closed, etc.) that is input in the host computer control system in advance in the current classroom at the current time period until the fan generates noise. The size of the noise meets the requirements of the corresponding state.
所述控制单元还包括存储模块和记忆模块，当有人为调整时，控制系统会将传感器采集的信息分析处理，随后将运算结果及调整前后的状态信息保存到数据库中，控制系统分析数据库，逐步调整相关参数，进而完成记忆学习改进的过程，使得系统愈来愈智能，更加符合人们使用习惯，同时智能处理不合理的人为调节。The control unit also includes a storage module and a memory module. When someone manually adjusts, the control system will analyze and process the information collected by the sensor, and then save the calculation results and the status information before and after adjustment in the database. The control system analyzes the database and gradually Adjust the relevant parameters, and then complete the process of improving memory and learning, making the system more and more intelligent, more in line with people's usage habits, and intelligently deal with unreasonable human adjustments.
